MEASURING-MACHINE.

Specification of Letters Patent.

Patented Apr. 18, 1916.

Application filed April 30, 1913. Serial No. 764,534.

To all whom it may concern:

Be it known that I, FRANK H. Train, a citizen of the United States, residing in Salem, in the county of Essex and State of Massachusetts, have invented an Improvement in Measuring-Machines, of which the following description, in connection with is a specification, like characters on the drawings representing like parts.

'This invention relates to measuring machines ofthat class in which is' employed a power operated bed roll and a plurality of measuring wheels or devices, between which and the bed roll the hide or skin to be meas ured is passed. The well known Sawyer measuring machine is of this type.

The present invention has for its object to increase the accuracy and output of machines of the class referred to, and to render them easier to operate.

In operation with measuring machines of the Sawyer type, the hide or skin is inserted between the bed roll and the measuring wheels and is held back by both hands of the operator to place'the hide or skin under tension, and as a result the skin is" often times presented to the measuring wheels more or less wrinkled with consequent loss of surface measurement.

The present invention has for its object to avoid this objectionable feature of measuring machines of the class described, and provide for the hide or skin being presented to the measuring wheels under tension, in a smooth condition and in a uniform manner, whereby an increased surface measurement is obtained and a more accurate measurement of the hide or skin is effected with the machine, with less care on the part of the operator. To this end, measuring Inachines of the class described are provided with a feed mechanism, preferably rolls, which are located at the front of the machine between the usual table and the bed roll, and one of said feed rolls is preferably driven at a slower speed than the bed roll, so as to hold back on the hide or skin and place that portion between the bed and feed rolls under tension. One of the feed rolls is smooth to engage the grain side of the hide or skin and avoid marking or injuring the same, and the other may be smooth or provided with means for laterally spreadmg the hide or skin.

The particular features of the invention w1ll be pointed out in the claims at the end of this specification.

Figure 1 is a vertical section of one form of measuring machine. embodying this invention; Fig. 2, an enlarged detail to be referred to, and Fig; 3, a modified form of feed roll to be referred to.

The machine herein shown is of the Sawyer type and more particularly is that shown and described inU; S. Patent No. 931,144 dated Aug. 17, 1909, and is provided with the bed roll a measuring wheels I) and toothed wheels 0, which latter are driven from the measuring wheels I) by pinions d.

The bed. roll is rotated by power, and the other parts of the machine are operated as fully described in the patent referred to, and do not require further explanation in the present case The bed roll a and measuring wheels I) have cooperating with them two feed rolls 10, 12, which are arranged at the front of the machine between the bed roll a and the usual table 6 and are journaled at each end in boxes 13, 14, located in openings 15 in frames 16, only one of which is shown. The frames 16 are bolted or otherwise secured to the side frames 17 of the machine, only one of which is shown, and the boxes 13, 14 are adjustably supported in the frames 17, which is accomplished as herein shown by a set screw 20 engaging each of the upper boxes 13, and by a spring 22 engaging each of the boxes 14, each spring being backed up by a set screw 23 by means of which the roll 12 can be forced toward the roll 10 with different degrees of pressure.

The rolls 10, 12 constitute feed rolls for the hide or skin 24, and they may be rotated in any suitable or well known manner but preferably at a slower speed than the bed roll, and in the present instance the lower feed roll 12 is represented as driven from the bed roll bv the link chain 25.

The lower feed roll 12 may be a felt roll as herein represented, with which the grain side of the hide or skin 24- is engaged, so as not to mark the grain surface, and the upper feed roll 10 may be of metal and provided with a smooth surface, as shown in Figs. 1 and 2, or it may be provided with helically arranged working edges 50 after the manner of the well known work roll of hide and leather working machines as shown in Fig. 3.

In operation, the feed rolls-10, l2 feed the hide or skin 24 to the bed roll a and between the latter and the measuring wheels 6, and

as soon as the hide or skin is engaged with the bed roll and measuring wheels a drag or tension is placed on the hidevor skin, and the operator is allowed to employ both hands in smoothing out the skin on the table e, thereby putting it in a superior condition to be measured and consequently obtaining with the machine a greater surface measurement and a moreaccurate one.

If desired the roll 10 may be provided with spreading edges .as above described to assist the operator 1n smoothing out the wrinkles.

t will be observed, that by means of the feed mechanism, the work of measuring the,

measurement over thesupport.

Claims: 1. In a measuringmachine ofthe class described, in combination, a rotatable bed roll, rotatable measuring devices cooperatingtherewith, atable to support the .work, feed rolls interposed between said table and bed roll and measuring devices, yielding means :for automatically ,moving one feed roll toward the other, and means for-posi- -tiv,ely rot-atlng one of said feed rolls at a slower peripheral speed than said-bed roll. '2. In a measuring machine of the class described, in combination, a rotatable :bed

roll, rota-table measuring devices cooperating therewith, rand feed rolls cooperating -measuring devices, one of said feed rolls being driven at a slower speed than said bedroll.

In testimony wheneof, I have signed my nameto this specification in the presence .of

two subscribing witnesses.
